Layer 2 Tunneling Protocol Version 3 Extended Circuit Status Values
RFC 5641, “Layer 2 Tunneling Protocol Version 3 Extended Circuit Status Values”, is a Proposed Standard document published in August 2009 by N. McGill, C. Pignataro. It updates RFC 3931, RFC 4349, RFC 4454, RFC 4591, RFC 4719. The canonical text is published by the RFC Editor.
Abstract
This document defines additional Layer 2 Tunneling Protocol Version 3 (L2TPv3) bit values to be used within the "Circuit Status" Attribute Value Pair (AVP) to communicate finer-grained error states for Attachment Circuits (ACs) and pseudowires (PWs). It also generalizes the Active bit and deprecates the use of the New bit in the Circuit Status AVP, updating RFC 3931, RFC 4349, RFC 4454, RFC 4591, and RFC 4719. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
